3-(Trifluoromethyl)benzophenone phenyl-(3-trifluoromethyl-phenyl)-methanone 3-(trifluoromethyl)-benzophenone Phenyl[3-(trifluoromethyl)phenyl]methanone Phenyl(3-(trifluoromethyl)phenyl)methanone m-(Trifluoromethyl)benzophenone 728-81-4 (CAS 728-81-4) is a high-purity analytical reference standard with the molecular formula C14H9F3O and a molecular weight of 250.22 g/mol.
The molecular framework of 3-(Trifluoromethyl)benzophenone phenyl-(3-trifluoromethyl-phenyl)-methanone 3-(trifluoromethyl)-benzophenone Phenyl[3-(trifluoromethyl)phenyl]methanone Phenyl(3-(trifluoromethyl)phenyl)methanone m-(Trifluoromethyl)benzophenone 728-81-4 (C14H9F3O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 3-(Trifluoromethyl)benzophenone phenyl-(3-trifluoromethyl-phenyl)-methanone 3-(trifluoromethyl)-benzophenone Phenyl[3-(trifluoromethyl)phenyl]methanone Phenyl(3-(trifluoromethyl)phenyl)methanone m-(Trifluoromethyl)benzophenone 728-81-4 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
